Webk, the Rate Constant We can determine a rate constant from a differential rate law by substituting a rate and the corresponding concentrations (for example, data from any of the experiments above) into a rate law and solving for k. Using the data from experiments 1, 2, or 3 we could solve the following equation for k: Top WebThe slope of the straight line corresponds to the negative rate constant, – k, and the y -intercept corresponds to the natural logarithm of the initial concentration. Figure 17.7. “Concentration vs. Time, First-Order Reaction.” This graph shows the plot of the natural logarithm of concentration versus time for a first-order reaction. Example 17.4
